Translating a Stem Cell-Based Therapy for Epidermolysis Bullosa into the Clinic

Abstract

The proposal develops a stem-cell based therapy for recessive dystrophic epidermolysis bullosa (RDEB), which is one of the most severe forms of epidermolysis bullosa (EB), a group of rare inherited skin blistering diseases. To accomplish this goal, we are utilizing genetic correction of patient-specific induced pluripotent stem cells (iPSCs) followed by the differentiation of these corrected iPSCs into epidermal cells and fibroblasts for the generation of composite full thickness skin grafts for transplantation. During the first year, we have secured approval for our ACURO protocol to use animals (ACURO Log Number PR171428.e001, approved on 10/01/2019), and are currently waiting for the IRB approvals from our collaborating groups from Stanford and Columbia Universities to address HRPO concerns. While our human subject protocol was awaiting approval by the DOD, we focused on tasks that did not require human subject participation. Specifically, we validated antibodies necessary to accomplish the project; we are also transferring our protocols for the generation of iPSCs and iPSC-derived keratinocytes into the Gates Biomanufacturing Facility (GBF) to implement a pilot cGMP run; and we have finalized the protocol for the differentiation of iPSCs into fibroblasts. We have also assessed several matrices to generate full thickness skin equivalents for the proposed research.
